A resistance circuit is configured such that a P-type resistance section and an N-type resistance section are electrically connected in series, the P-type resistance section is configured with P-type diffusion layer resistance elements that are disposed to form a right angle with respect to each other and that are electrically connected in series, and the N-type resistance section is configured with N-type diffusion layer resistance elements that are disposed to form the right angle with respect to each other and that are electrically connected in series. Furthermore, the P-type diffusion layer resistance element is disposed along a &#x3c;100&#x3e; orientation direction of a semiconductor substrate, and the N-type diffusion layer resistance element is disposed along a &#x3c;110&#x3e; orientation direction of the semiconductor substrate. It is thereby possible to provide the resistance circuit, an oscillation circuit, and an in-vehicle sensor apparatus that reduce stress-induced characteristic fluctuations.
